DUMPING APPARATUS.

$PECIFICATION forming part of Letters Patent No. 370,624, datedSeptember 27, 1887. Application filed January 14, 1887. Serial No.224,365. (No model.)

To all whom it may concern:

Be it known that I, GEORGE H. HULETT, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio,haveinvented certain new and useful Improvements in Dumping Apparatus, ofwhich the following is a specification, reference being had therein tothe accompanying drawings, in which- Figure 1 represents a side view ofmy apparatus with the door closed; Fig. 2, a similar view with the dooropen, and Fig. 3 a rear View with door open.

This improvement relates to a dumping-hopper and car, which hopper isautomatically opened and closed by the movement of the car as it passesunder and is withdrawn from under the hopper; and the invention consistsin the peculiar combinations and construction and arrangement of parts,hereinafter more particularly described, and then definitely pointed outin the claims.

Referring now to the details of the drawings, A represents thehopper,which is securely held by suitable supports, B, and is providedwith a swinging convex bottom or door, 0, hinged at c andcounterbalanced, so as to move easily in any convenient Way, butpreferably by a weight, D, hung from a cord or chain, E, attached to thefront of the swinging bottom 0, and passing over a pulley, F, attachedto the hopper A or some part of the frame.

Hung from the sides of the hopper is a stirrup, G, formed of two bars,g, connected at their lower ends by a rod, H, on which are journaled two(preferably grooved) rollers, h, which rollers run underneath the convexbottom of the car on curved bars I, securely attached to said bottom.

At J is shown a car,of any appropriate or approved form, provided with a(log, K, pivoted at L to a ,fixed bar, M, which bar is provided with astop of any approved form- -such as the pin N the whole being soarranged that the dog will readily swing over in one direction, but isrigid in the other.

0 represents a rigid .post or bar, whose use will be hereinafterexplained.

The operation is as follows: Suppose the hopper-bottom to be closed, asshown in Fig. 1, and the hopper full of coal or ore. The car J is pushedunder the hopper and the dog K tilts, as shown in dotted lines, as itpasses under the rod H, so that it has no action on the rod or stirrupG, and passes under it without effecting anything; but the post 0, whenit comes in contact with the rod H, moves it and the stirrup backward,and thus the bottom of the hopper is allowed to drop with the weight ofthe coal contained in the hopper. As soon as the hopper has emptied itscontents into the car, the latter is drawn out, and the dog K,being nowrigid and coming in contact with the rod H, pushes it and the stirrup Gback to its original position, thus closing the swinging bottom,whichwill take but very little power, as the bottom is counterbalanced by theweight D.

It is obvious that there is no absolute necessity of the bottom beingconvex, as it may be fiat and the bars or ways I made convex.

I prefer to make the ways nearly or quite straight for about one-half oftheir length; but

the front part should be curved substantially on the same line as thatwhich the rod H-describes as it moves from front to rear, or thereverse.

From this it will be seen that Ihave provided a very convenientautomatically-opening door to my hopper that is not only very convenientin use, but, although comparatively cheap in construction, is verydurable and not likely to get out of order.

Having thus pointed out what I consider the preferable form of myimprovement, but without limiting myself to the construction shown, whatI claim as new is 1. A hopper provided with aswinging door, combinedwith a vibrating stirrup rolling under said door for securely fasteningthe same, substantially as described.

2. The combination of a hopper provided with a swinging door and afastening therefor,

with a car independentfiof said hopper,having a device for operating thefastening, substantially as described.

3. The combination, with a hopper having a falling bottom and a swingingstirrup, of a car provided with a rigid post and a pivoted dogco-operating with said stirrup, substantially as described.

4.. In a dumping apparatus, and in combi- ICO nation with a hopperhaving a door and vibrating fastening, a car provided with a dog, K,adapted to swing in one direction and be held rigid in the other toco-operate with said door-fastening, substantially as described.

5. In a dumping apparatus, the combination, with a hopper provided witha counterbalanced door, of a swinging stirrup,and a car provided withmeans for operating said stirrup, substantially as described.

6. In a dumping apparatus, the combination of a hopper provided with aswinging bottom and a swinging stirrup provided with rollers running oncurved ways, substantially as described.

7. The combination, in a dumping appa-
